Detailed Description

The LabeledPairFinder allows the matching of labeled features (features with a fixed distance).

Finds feature pairs that have a defined distance in RT and m/z in the same map.

Parameters of this class are:

NameTypeDefaultRestrictionsDescription
rt_estimate stringtrue true, falseIf 'true' the optimal RT pair distance and deviation are estimated by fitting a gaussian distribution to the histogram of pair distance. Note that this works only datasets with a significant amount of pairs! If 'false' the parameters 'rt_pair_dist', 'rt_dev_low' and 'rt_dev_high' define the optimal distance.
rt_pair_dist float-20.0  optimal pair distance in RT [sec] from light to heavy feature
rt_dev_low float15.0 min: 0.0maximum allowed deviation below optimal retention time distance
rt_dev_high float15.0 min: 0.0maximum allowed deviation above optimal retention time distance
mz_pair_dists float list[4.0]  optimal pair distances in m/z [Th] for features with charge +1 (adapted to +2, +3, .. by division through charge)
mz_dev float0.05 min: 0.0maximum allowed deviation from optimal m/z distance
mrm stringfalse true, falsethis option should be used if the features correspond mrm chromatograms (additionally the precursor is taken into account)

Note:
  • If a section name is documented, the documentation is displayed as tooltip.
  • Advanced parameter names are italic.
Todo:

Implement support for labeled MRM experiments, Q1 m/z value and charges. (Andreas)

Implement support for more than one mass delta, e.g. from missed cleavages and so on (Andreas)

private

Assignment operator not implemented => private.

◆ PValue_()

double PValue_ ( double  x,
double  m,
double  sig1,
double  sig2 
)
inlineprotected

return the p-value at position x for the bi-Gaussian distribution with mean m and standard deviation sig1 (left) and sig2 (right)

◆ run()

void run ( const std::vector< ConsensusMap > &  input_maps,
ConsensusMap result_map 
)
overridevirtual

Run the algorithm.

Note
Exactly one input map has to be provided.
The output map has to have two file descriptions, containing the same file name. The file descriptions have to be labeled 'heavy' and 'light'.
Exceptions
Exception::IllegalArgumentis thrown if the input data is not valid.

Implements BaseGroupFinder.
